Spin uncoupling
WebJul 20, 2024 · The source of signal splitting is a phenomenon called spin-spin coupling, a term that describes the magnetic interactions between neighboring, non-equivalent NMR-active nuclei. (The terms 'splitting' and 'coupling' are often used interchangeably when discussing NMR.) WebDec 28, 2001 · These values are corrected for spin-uncoupling effects in the ground state and represent our best estimate of the true bond length of WC. Dispersed fluorescence studies provide the ground-state vibrational constants of ω e =983 (4) cm −1 and ω e x e =11 (1) cm −1, and have also permitted the low-lying [1.2] 3 Δ 2 and [4.75] states to be ...

WebFeb 5, 1996 · We propose a general definition of spin-catalysisas phenomena in which chemical reactions are promoted by substances which assist in overcoming spin-prohibition or in which the activation barrier is lowered through spin uncoupling induced by a paramagnetic catalyst.
WebSpin uncoupling in chemical reactions. Minaev, Boris F. ; Ågren, Hans. Spin pairing is the main attribute of the covalent chemical bond. Exchange repulsion between closed shell molecules being responsible for activation barriers in bimolecular reactions can be explained by a high weight of the intermolecular triplet spin pairing.
